Overview:Four top predators are compared, each champion in a type of environment, with key adaptations. On the ground, the cheetah outruns prey (approached in masterly stealth) and enemies. In the air, the peregrine falcon is a flight and diving machine. In sweet water, the Nile crocodile survives since the Dino age, without natural enemies, with several amazing metabolism stunts. Lurking under water, it snaps blindly at migrating wildebeest, then waits underground. In the oceans, the equally ancient shark, notably the great white, migrates seasonally to find abundant prey, such as young seals around South Africa.
